Vga cable doesn't work mini

I have a mac mini and I purchased the mini display port to vga cable for it. When I start the mac, I get the apple logo and then the screen goes blank. I have connected the mini to my tv using a hdmi cable and that is working.

Try resetting the NVRAM / PRAM, as per > About NVRAM and PRAM
Are you using Apple's > Mini DisplayPort to VGA Adapter and a VGA cable or an aftermarket DisplayPort to VGA cable...?

  • I have a VGA adapter and an iPad2.  Tried projecting my iPad2 to projector using the VGA but doesn't work.  Tried it with friend's iPad1 and it works.  Why??

    I have a VGA adapter and an iPad2.  Tried projecting my iPad2 to projector using the VGA but doesn't work.  Tried it with friend's iPad1 and it works.  Why??  Pls help.

    Yup - nothing happens.  I then took the same VGA cable and plugged it into my friend's iPad1 and it worked perfectly when she opened Keynote.  My understanding is that the iPad2 mirrors the entire screen, so no need to go into any specific application in order to project to the screen, right?  Do I need to download any specific app or change any settings in order to be able to project the screen using VGA?
    Sorry - novice at this.  Not very tech minded either...

  • Upgraded to iOS6 and now charging cable doesn't work

    I just upgraded to iOS6 n my iPhone 4, and now my charging cable doesn't work.  No...it's not an "official" Apple charger, but even the usb cable doesn't work when I plug it into my computer.  If I plug my iPad charger into it, it works fine.  How can the new operating system determine what kind of usb charging cable it "wants" to accept?  This charger and cable worked flawlessly before the OS upgrade.

    Same problem here. I use a wall charger and have had success by unplugging the charger from the wall, plugging the adapter into the iPhone, then plugging charger back into wall. Had the same problem with a car charger and got the phone to charge using the same procedure. I'd love to know if this works for you. Good luck!

    Try updating the carrier settings, if that doesn't do it try following along with this Apple doc -> iOS: Troubleshooting Personal Hotspot

    if my charging cable doesn't work do i get a new for free

    I had a lightning cable, that came with my iPhone 5s, that frayed and broke at the connector.  I took the cable and phone into the Apple Store and they exchanged the cable for a new one with not a question asked.  Good experience.
    I think part of it is that the design of the Apple cables is quite flimsy especially at the connector and I think they see a lot of them fail.

    It's covered under the same warranty as the phone. So long as it's not physically damaged, they should replace it for you.

  • Mini DVI to VGA cable doesn't send signal to the projector

    I just received a mini DVI to VGA adapter cable today.
    I connect mini DVI side of cable into my Macbook v. 4.1 and connect the other side into DGA cable, which connected to LCD projector.
    When I connect the cable to my Macbook, the opened application streched out to a full screen (seems like computer detets the cable) but projector says 'no signal'.
    Can any one tell me what is wrong it is?
    Thanks much
    Mike

    I'm still stucked.
    By reading some articles, it says even using mini DVI adapter, the signal is still digital and if the projector doesn't accept digital signal then it's no use....
    My projector is Epson EX3200 and it doesn't have any DVI or HDMI input.
    Does this mean my projector doesn't accept a digital signal?
    But, but, but if even uing mini DVI adapter cable it still doesn't conver to analog signal then why they call the cable a mini DVI to VGA cable???
    Why should this world be so complecated.....

    If it is showing the Galaxy image the signal is getting there. you have it set to Extended desktop. Go into the Dispplay section in System Preferences and chnge it to Mirror display, Check Box near the bottom of that window.

  • Dr. Bott Mini DisplayPort to HDMI cable doesn't work.

    I'm trying to connect my MacBook (mid 2010) with my tv and I can't get it working properly. I have the HDMI cable, and the mini display port to the HDMI cable. When I connect the computer to the tv, the computer screen turns light blue like it is about to synchronize, but the tv screen remains black. After a moment, 2 boxes appear on my tv screen. One says "HDMI1: and  the other "no signal detected".
    I've tried with "detect displays", I've tried connecting to all the HDMI ports I have on my TV, I've tried basically everything but it still doesn't work.
    This is the adapter - http://www.drbott.net/product/7395-MDPA/
    My TV is a fairly new Samsung, and everything else is working fine, I don't know why this won't function. It's frustrating me.
    Any help on this matter would be greatly appreciated. Thanks.

    When I have this problem, it is because my Macbook Pro is using "Integrated" graphics vs the "Descrete" graphics.  I control this via the gfxCardStatus menubar utility.
    You could also try reseting the smc controller

    and/or resetting the PRAM

  • VGA cable no longer working with IOS8

    VGA cable that I have (that used to always work), no longer works with ANY projector.  Either get zero recognition or popup saying it "doesn't support that application".  It is an Apple VGA cable.  Thoughts?  Thank you....

    Other folks have reported problems with older cables when using 8.x.  You can wait and see if apple eventually fixes or go to an apple store and buy a new cable.  Got to get the latest firmware on the cable. You could buy apple tv or chromecast ( more difficult to configure ).

  • IPod to TV using digital camera cable, doesn't work. Help

    Hey
    I've got the iPod 5th Generation 30Gb video. I ripped one of my DVDs onto my computer and then used videora to convert the DVD for use on the ipod. I used iTunes to stick the movie on my iPod.
    The movie plays fine on the ipod, but when I go to connect the iPod to my LG Flatron TV it doesn't work. I am using a cable that came with my digital camera, it only has one black and one yellow rca plug. If I use it with the camera, the black is for video, and the yellow for audio. But on the ipod, I don't get anything. I have checked that the send to TV settings are On.
    I've tried changing the format on the output from PAL to NTSC, nothing.
    One thing I am not sure about is why my cable has got a little box thingy surrounding part of the wire, inside the box thingy are magnets, anyone know why these are here? Could this be what is causing it not to work. What should I do?
    Thanks

    Here is some info for the pinout for the iPod.

    You need to find the pinout of the camera cable you have.
    Probably be easier to get get an AV cable with a 3.5mm plug to (whatever fits into your TV) cable.
    Usually, you simply have to swap the Red and the Yellow for it to work properly.

  • IPod Nano Video-Out to TV (Via new Apple Component cable) DOESN"T WORK

    It doesn't work on my nano. The sound plays fine, the video is distorted. It isn't the cable, since I have an iPod Touch that displays fine.
    I've tinkered with the settings : Widescreen, NTSC, Fit to Screen, etc... none of it helps. Still shows a distorted image (like when a computer displays the wrong resolution on a screen, or the way a channel on Cable looks if you aren't subscribed to it).
    Is my Nano defective? Am I going to have to rally up several other Nano users with similar issues, post it up on my blog?
    Anyone can help me?
    Also, my iPod Touch doesn't display photo transitions (cube, wipe, etc) only fades.... even though I've attempted switching the settings. Only works when the component cable is disconnected. Any help on this too?

    Did you check the settings on the TV itself? Are you feeding the video through a A/V receiver?
    Those may also be distorting your picture.
    In my case, I'm going from my Nano>Yamaha A/V receiver>Mitsubishi 65" WS TV.
    Once I set my receiver up, and set my TV to standard, I was getting a distortion-free picture (at least with the "Jack-Jack" short that I got free from iTunes). My setting in the Nano were WS & NTSC. Everything was cool (I was surprised on how good the picture looked, but then my Yamaha is great for upscaling).
    I don't know if this helped, but if you list a little more about your config, I might be able to assit better.

  • 30-pin cable doesn't work in battery charing

    I have bought an official cable and a unofficial cable and I am iphone 4 user. I can't charge my phone with both cable. This is iOS 7 and I restored so many times. Can you tell me how to fix the problem?

    Ok, Is your computer on? If so try putting it in a different USB port. If that doesn't help, try cleaning this part. If that doesn't work, Your battery may be fried.
